LIGHTING ATTACHMENT FOR SOUND-REPRODUCING MACHINES.

Application filed October 18, 1917.

To aZZ'w/wm it may concern:

Be it known thatI, Gnoncn E. Bnnnnonnn, a citizen of the United States,residing at Milwaukee, in .the county of lvlilwaukee and State ofWisconsin, have invented new and useful Improvements in LightingAttachments for Sound-Reproducin Machines, of which the following is aspecification.

This invention relates to lighting attachments forsound reproducingmachines.

One oi the objects of the invention is to provide an improved lightingattachment which may be used with any type of sound reproducing machine.

Another object is to provide a lighting attachment which may be readilyapplied, easily operated, applies light where and when needed and whichis of improvcdappearance.

Another object is to provide improved switching means for opening andclosing the circuit of the light.

Other objects will appear from the fol lowing specification and claims.

In the drawings Figure 1 is a viewof the complete lighting attachmentmounted on the table of a sound reproducing machine.

Fig. 2 is a perspective of the complete lighting attachment. 1

Fig. 3 is a vertical section through the center of the attachment.

. Fig. 41 is a disassembled perspective show ing the relation and methodof assembling the parts."

Fig. 5 is a bottom attachment, and

Figs. 6 and 7 are views of the insulators used.

The attachment comprises a tubular standard 5 having an enlarged hollowbase 6 and an enlarged barrel 7 at its upper end. The base 6 is providedwith openings 8 through which screws may be passed to secure theattachment to the table of the sound reproducing machine.

The barrel 7 is provided with an opening 10 in itsfront wall throughwhich the electric light can project as hereinafter described. The rearwall of the barrel 7 has a cut-away portion or notch 11 the lower edgeof which is inclined as shown at 12. An insulating sleeve 15 encirclesthe outer plan of the cap of the wall of barrel 7. This sleeve isprovided with an opening 16 registering withopening 10, and a notch orcut-away portion 17 Specification of Letters Patent.

registering with the cutaway portion 11 01 barrel 7. This sleeve is madefrom punched strips of paper such as shown in Fig. 6, the round opening16 being formed by the placing together of the two ends of a punchedpaper strip so that the semi-circular cut in each is opposite andcomplementary of each other. The upper part of the attachment comprisesa cap 20 adapted to he slipped over the barrel 7 and insulator l5 andclose the upper end of the standard. The cap is provided in its forwardface with a tubular sleeve 21 into which may beforced the lamp socketand a light projector 22. The socket 22 is adapted to be readilyinserted and removed from the sleeve 21 and when in position the lamp 23and lamp terminal-2 1 do not touch the wall or opening 10 in barrel 7.

The cap 20 has pivoted to the center of its top a switch arm 25. Thisswitch arm projects through a slot 26 in the rear wall of the ca whereit may be manipulated by the fingers. A paper insulating washer 27 liesin the top of the cap between its top wall and arm and prevents theupper edge of barrel 7 from making contact with the upper wall of thecap. The leads 30 and 31, from a source of current such as a dry battery32 pass through a notch 33 in the base 6. Lead 31 is secured by asuitable terminal 35 to the base 6, while lead 30 is secured to theinner terminal of-the lamp.

In assembling the attachment the paper sleeve 15 is wrapped about barrel7. Cap 20 is then forced down over the sleeve 15 with its switch arm 25coming within the cutaway portion 11. The socket 22 is then forced intothe sleeve 21, the lead 30 having previously been secured to the lampterminal. When thus assembled as long as switch arm 25 is in the deeperportion of notch 11 the circuit of the lamp is open. WV hen, however,the switch arm 25 is turned to the left so that it rides upon theinclined edge 12 it will wedge between this edge and the upper edge ofthe slot 26 and a circuit will then be completed for the lamp asfollows: from lead 30 through the lamp, through socket 22 and sleeve 21to the cap 20, then from the upper edge'of slot 26 through the switcharm 25 to the inclined edge 12 of notch 11, then 7 through the barrel 7and standard 5 to the terminal 35 and then out through the lead 31.NVhen the switch arm 25 is moved into the deeper portion of the notch 11this circuit is broken as the current cannot then pass from the cap 20to the barrel 7. i

' This attachment may be applied to any of the well known types of soundreproducing machines, and the light will be projected upon the needleand record. The light may be readily turned OE and on by slight movementof the switch arm 25.

What I claim is:

1. A lighting attachment for sound reproducing machines, comprising ahollow, upright standard having a base adapted to rest upon the tabletop, a cap fitting over and closing the upper end of said standard, butinsulated therefrom, light projecting means supported by andelectrically con nected to said cap for illuminating a portion of themachine record, said standard and light projecting means adapted to beelectrically connected vwith the opposite terminals of a source ofcurrent, and a switch for opening and closing the circuit between saidcap and said'standard.

2. An attachment for lighting the records of sound reproducing machineshaving an electric light arranged to project light in only onedirection, an upright tubular standard supporting the light in positionabove and to the side of thelrecord, and having a cut-away portion atits upper end, a cap closing the upper end of the standard, insulatingmeans between the cap and standard, circuit connections inclosed by thestandard one secured to the light and one secured to said standard, anda switch arm pivoted to said cap and adapted to engage the standard ormove in the cut-away portion to make and break circuit for said light.3. A switch comprising a tubular body having an irregular cut-awayportion a cap fitting over and closing one end of said body, insulatingmeans between said body and cap, and having a cut-away portioncorresponding to the cut-away portion of said body, and an arm pivotedto said cap and movable withinthe cut-away portions of said body andsaid means and cooperating with said body to make and break contacttherewith.

'4. A lighting attachment for sound reproducing machines comprising anelectric light, a tubular standard supporting the light in projectingposition, a cap covering the upper end of said standard, said'cap Copiesof this patent mayc be obtained for standard adapted to rest on thetable of the 7 machine, means for projecting;- light upon the record, acap fitting over the upper end of said standard and normally insulatedtherefrom, a switch for completing an elec tric circuit between thestandard and the cap and means whereby the attachment may beelectrically connected to a source of cur-' rent which is separate fromsaid attachment.

6. A lighting attachment for sound reproducing .machines, comprising astandard adapted to rest on the table of the machine, means forprojecting light upon the record, a cap for said standard and normallyinsulated therefrom, a switch -member movable to and adapted to remainin either of two positions, means whereby said switch member in one ofits positions will establish an electrical connection between thestandard and the cap, said connection being broken when the switchmember is in its other position. and means whereby the attachment may beelectrically connected to a source of current which is separate from theattaclnnent. i

7. A lighting attachment for sound reproducing machines, comprising avertical, tubular standard ladapt'ed to rest on the tableof'the'machine, means for projecting light upon the record, a capfitting over the upper end of said standard and normally insulatedtherefrom, a switch lever pivoted to the top ofsaid cap and projectingradially from the cap and means whereby said switch arm in one positionwill establish an electrical connection between the standard and thecap, said connection being broken in another position of said switcharm.

In witness whereof, I have hereunto subscribed my name.
